Jordi Baylina

Who Is Jordi Baylina?

Jordi Baylina is a blockchain developer, zero-knowledge proof engineer, Ethereum community contributor, and one of the best-known technical builders behind Polygon zkEVM, Hermez, iden3, Circom, snarkjs, and ZisK.

He is not a cryptocurrency, token, wallet, private key, seed phrase, mining pool, validator, smart contract address, or trading strategy.

In crypto, Jordi Baylina is important because his work sits close to the technical foundation of Ethereum scaling, zero-knowledge proofs, privacy-preserving identity, and verifiable computation.

The official ZisK website describes ZisK as an open-source zero-knowledge proving toolstack with a zkVM that enables verifiable execution of programs written in high-level languages such as Rust.

The ZisK GitHub organization states that ZisK was incubated by Polygon Labs from May 2024 to June 2025 and became an independent project on June 13, 2025.

For crypto users, the simple meaning of Jordi Baylina as a glossary term is that he is a major zero-knowledge infrastructure builder whose work helps blockchains become more scalable, verifiable, private, and useful.

Why Jordi Baylina Matters in Crypto

Jordi Baylina matters because many of crypto’s hardest problems require deep engineering rather than marketing.

Ethereum and other smart contract networks need to process more transactions, lower user costs, preserve security, support private computation, and give developers tools that are powerful enough for real applications.

Zero-knowledge proofs are one of the main technologies used to solve these problems.

Baylina’s work has helped move zero-knowledge systems from academic cryptography toward practical blockchain infrastructure.

He has contributed to tools that developers use to write circuits, generate proofs, verify computation, and build scaling systems.

His name is often connected with zk-rollups, zkEVM design, ZK circuits, zkSNARK tooling, proof systems, and Ethereum community security work.

This makes him relevant to users even if they never write a line of code.

When a user interacts with a Layer 2 network, bridges assets, signs a transaction, uses a privacy-preserving identity tool, or relies on fast Ethereum settlement, they may indirectly depend on engineering ideas that Baylina and other ZK builders helped popularize.

Jordi Baylina and Polygon zkEVM

Polygon zkEVM is one of the major projects associated with Jordi Baylina.

The official Polygon zkEVM announcement described Polygon zkEVM as an Ethereum-equivalent scaling solution designed to work with existing smart contracts, developer tools, and wallets while using zero-knowledge proofs.

A zkEVM is a zero-knowledge Ethereum Virtual Machine that aims to prove Ethereum-style execution with cryptographic validity proofs.

This matters because Ethereum applications are usually written for the EVM.

If a scaling system can support EVM-compatible or Ethereum-equivalent execution, developers may be able to move or deploy applications more easily.

Baylina’s work on Polygon zkEVM is important because it addressed one of the biggest technical challenges in blockchain scaling.

The challenge was to keep Ethereum developer compatibility while using zero-knowledge proofs to verify large batches of transactions efficiently.

For users, zkEVM technology can mean lower fees, faster confirmation experiences, and stronger cryptographic settlement assumptions.

However, users should still understand bridge risk, smart contract risk, sequencer risk, liquidity risk, and network-specific rules before moving large amounts to any Layer 2 system.

Jordi Baylina and Hermez

Hermez was a zero-knowledge rollup project focused on scaling Ethereum transactions.

Jordi Baylina was closely connected with Hermez before it became part of the broader Polygon zero-knowledge ecosystem.

Hermez helped bring practical zk-rollup ideas into production-focused Ethereum scaling conversations.

A zk-rollup moves transaction computation off Ethereum mainnet while publishing proofs and data that allow Ethereum to verify correctness.

This can reduce costs because the base chain does not need to execute every transaction one by one.

Instead, it can verify a compact proof that represents the validity of many operations.

Baylina’s Hermez work matters because it helped demonstrate that zero-knowledge proofs could be used for real blockchain scaling rather than only theoretical privacy systems.

Hermez also reflected a broader Ethereum value of open-source infrastructure and community-oriented development.

Users should understand that a zk-rollup is not magic because it still needs secure contracts, reliable provers, safe bridges, clear governance, and careful monitoring.

Jordi Baylina and ZisK

ZisK is the current project most closely connected with Jordi Baylina’s latest public technical work.

The official ZisK homepage presents ZisK as a zero-knowledge proving toolstack focused on real-time proving and high-level language support.

The ZisK GitHub organization profile says the project became independent on June 13, 2025 after being incubated by Polygon Labs.

ZisK is important because modern blockchains increasingly need fast proof generation.

If proofs are slow, users may face delayed withdrawals, slower finality, weaker user experience, or higher infrastructure costs.

A zkVM can help developers prove that a program executed correctly without requiring every verifier to rerun the full computation.

This is useful for blockchain scaling, verifiable computation, privacy-preserving applications, rollups, cross-chain proofs, and trust-minimized infrastructure.

Baylina’s move toward ZisK shows that the zero-knowledge field is shifting from proving small circuits toward proving larger and more flexible programs.

For users, this matters because faster and more flexible proof systems can eventually make blockchain applications feel cheaper, safer, and more scalable.

Jordi Baylina and Zero-Knowledge Proofs

A zero-knowledge proof is a cryptographic method that lets one party prove a statement is true without revealing all the underlying information.

The official Ethereum zero-knowledge rollups documentation explains that ZK-rollups post validity proofs to Ethereum so the base chain can verify the correctness of off-chain computation.

Zero-knowledge proofs can support both scalability and privacy.

In scalability use cases, proofs help verify many transactions with less on-chain computation.

In privacy use cases, proofs can show that a user meets a condition without revealing unnecessary personal data.

Jordi Baylina is important because he has worked on both sides of this technology.

His tools and projects connect ZK proofs with Ethereum scaling, circuit writing, identity, proof generation, and developer infrastructure.

Users should understand that zero-knowledge does not always mean private by default.

Some ZK systems are designed mainly for scalability and may still publish transaction data openly.

Other ZK systems are designed to hide sensitive details while proving correctness.

Jordi Baylina and Circom

Circom is a circuit description language used for building zero-knowledge applications.

The official Circom documentation explains that zero-knowledge can prove circuit satisfiability, which means proving that a set of signals satisfies a circuit.

Jordi Baylina is widely associated with Circom and its early ecosystem.

Circom matters because zero-knowledge proofs usually require computations to be expressed as circuits.

This is difficult for many developers because normal application logic must be translated into constraints that a proof system can understand.

Circom made it easier for developers to describe those constraints and build ZK applications.

It has been used in privacy tools, identity systems, proof-of-knowledge applications, cryptographic experiments, and educational projects.

However, writing ZK circuits remains difficult.

An under-constrained circuit can allow invalid proofs, while an over-constrained circuit can reject valid cases.

Developers should audit circuits carefully and avoid assuming that a circuit is safe only because it compiles.

Jordi Baylina and snarkjs

snarkjs is another major tool connected with Jordi Baylina’s zero-knowledge work.

The official snarkjs GitHub repository describes snarkjs as a JavaScript and WebAssembly implementation of zkSNARK and PLONK schemes.

snarkjs is important because it gives developers tools for proof generation, proof verification, trusted setup ceremonies, and verifier generation.

For Ethereum developers, this matters because a ZK proof often needs to be verified by a smart contract.

A tool like snarkjs can help move from circuit design to proof artifacts and on-chain verification.

Baylina’s connection with snarkjs is important because it helped make zero-knowledge development more accessible to web and Ethereum developers.

Before tools like Circom and snarkjs became common, ZK development felt far more limited to cryptography specialists.

These tools lowered the barrier for builders, but they did not remove the need for serious security review.

ZK proof tooling can produce powerful systems, but mistakes in circuit design or verifier use can still create critical vulnerabilities.

Jordi Baylina and iden3

iden3 is an identity protocol project connected with privacy, self-sovereign identity, and zero-knowledge access control.

The official iden3 GitHub organization describes iden3 as a next-generation private access control system based on self-sovereign identity for decentralized and trust-minimized environments.

Jordi Baylina is known as a co-founder of iden3 in public ZK community profiles.

Identity is one of the most important non-trading use cases for zero-knowledge proofs.

A user may need to prove that they are over a certain age, belong to a group, live in a certain jurisdiction, hold a credential, or pass a requirement without revealing all personal details.

Zero-knowledge identity can help reduce unnecessary data exposure.

This is important because crypto users often interact with public blockchains where activity can be linked, indexed, and analyzed.

Better identity systems can support privacy-preserving compliance, token-gated access, reputation, governance, and user protection.

Users should still be careful because identity metadata can become sensitive if handled poorly.

Jordi Baylina and Ethereum Scaling

Ethereum scaling means increasing Ethereum’s ability to support users and applications without making the base chain too expensive or too slow.

Jordi Baylina’s work is directly connected with this problem through Hermez, Polygon zkEVM, ZisK, and ZK proof tooling.

Ethereum mainnet prioritizes security and decentralization, which can limit throughput during high demand.

Layer 2 systems help by processing transactions outside the base layer and settling them back to Ethereum.

ZK-rollups are especially important because they use validity proofs instead of relying only on long dispute windows.

This can make finality and withdrawal designs more efficient when implemented well.

Baylina’s role is important because building a zkEVM requires solving compatibility, proving, performance, data, and verification problems at the same time.

For users, Ethereum scaling is not just a technical debate.

It affects gas fees, transaction speed, DeFi access, NFT minting costs, gaming applications, and everyday wallet usability.

Jordi Baylina and zkEVM Design

A zkEVM tries to prove Ethereum Virtual Machine execution with zero-knowledge proofs.

The EVM was not originally designed to be easy to prove in cryptographic circuits.

This creates a difficult engineering problem because EVM execution must be translated into algebraic constraints that a proof system can verify.

The official Polygon zkEVM technical documentation repository describes proof recursion, aggregation, composition, and polynomial identity language concepts used in the proving system.

Jordi Baylina’s work matters because zkEVM design requires both low-level cryptographic understanding and Ethereum developer compatibility.

If the system is too different from Ethereum, developers must rewrite applications.

If the system is too strict about Ethereum equivalence, proving may become slower or more expensive.

Good zkEVM design is therefore a tradeoff between compatibility, performance, security, and developer experience.

Users do not need to understand every mathematical detail, but they should know that zkEVM systems are complex and require careful audits, monitoring, and staged deployment.

Jordi Baylina and PIL

PIL stands for Polynomial Identity Language.

It is a language used in some zero-knowledge systems to describe relationships that must hold inside a proving system.

Public profiles of Jordi Baylina often mention his work on PIL alongside Circom and zkEVM development.

PIL matters because proof systems need precise mathematical statements about what a valid computation means.

In a zkEVM, the proving system must show that many low-level execution steps followed the correct rules.

Polynomial identities can describe those rules in a way that proof systems can check.

This is not visible to end users, but it is critical for correctness.

If the mathematical rules are incomplete or wrong, the proof system could accept invalid execution.

Baylina’s connection to PIL highlights the depth of engineering needed to make Ethereum-style computation provable.

Jordi Baylina and the White Hat Group

Jordi Baylina is often described as a member or co-founder of the Ethereum White Hat Group.

Public ZK community materials, including the Zcon3 speaker highlight for Jordi Baylina, describe him as part of the White Hat Group and as a co-founder of iden3.

White hat security work matters because crypto systems can hold large amounts of value and can be attacked globally.

When smart contracts contain bugs, funds can be stolen or frozen quickly.

White hat hackers and security researchers can help identify vulnerabilities, rescue funds, and improve ecosystem security.

Baylina’s security background is important because zero-knowledge systems and smart contracts both require extreme care.

A small error in a smart contract, circuit, verifier, or trusted setup process can have major consequences.

Users should understand that serious builders often spend as much time thinking about failure modes as they do thinking about new features.

Jordi Baylina and Smart Contract Security

Smart contract security is a major theme in Jordi Baylina’s crypto relevance.

Smart contracts are programs that can hold and move digital assets automatically.

Once deployed, a contract may be difficult to change, and user funds may depend on every line of logic working correctly.

Baylina’s Ethereum security and ZK background shows why careful review matters before users trust a protocol.

Security in crypto includes code audits, formal reasoning, bug bounties, testing, access controls, upgrade policies, and incident response.

For ZK systems, security also includes circuit correctness, verifier correctness, trusted setup safety, cryptographic assumptions, proof generation, and public input handling.

Users should never assume that a protocol is safe only because it uses advanced cryptography.

Advanced cryptography can strengthen a system, but it can also hide complexity that normal users cannot inspect easily.

The safest approach is to check audits, documentation, incident history, and official links before interacting with a protocol.

Jordi Baylina and zkVMs

A zkVM is a zero-knowledge virtual machine that can prove the correct execution of programs.

ZisK is an example of a zkVM-focused project connected with Jordi Baylina.

zkVMs are important because they may let developers write programs in more familiar high-level languages and generate proofs of execution.

This can be more flexible than writing custom circuits for every application.

A zkVM can support verifiable computation, rollup proving, cross-chain verification, private computation, and trust-minimized application logic.

The challenge is performance.

Proving general computation can be expensive, and real-time proving is a difficult goal.

Baylina’s current work on ZisK matters because it focuses on making proof generation faster and more practical.

If zkVMs become efficient enough, they could become a major building block for blockchain scaling and verifiable internet infrastructure.

Jordi Baylina and Open-Source Crypto Infrastructure

Jordi Baylina is strongly associated with open-source crypto infrastructure.

Open-source software matters in crypto because users and developers need transparency around code that can control financial value.

Tools such as Circom, snarkjs, Polygon zkEVM components, and ZisK-related code reflect the importance of shared technical foundations.

Open source helps developers inspect code, learn from implementation details, report bugs, and build compatible tools.

It also allows attackers to study code, which means open-source projects still need strong security processes.

Open source is not a guarantee of safety by itself.

It is a foundation for review, collaboration, and accountability.

Baylina’s career shows how open-source ZK tooling can accelerate the entire Ethereum and Web3 ecosystem.

Jordi Baylina and Privacy

Privacy is one of the main reasons zero-knowledge proofs are important.

Public blockchains are transparent, which helps verification but can expose user behavior when wallet addresses become linked to real identities.

Zero-knowledge tools can help users prove facts without revealing more information than necessary.

Jordi Baylina’s work with iden3 and ZK tools is relevant because identity and privacy are closely connected.

A privacy-preserving system might prove that a user meets a requirement without revealing the user’s full identity or complete wallet history.

This can help protect users from surveillance, profiling, phishing, and targeted attacks.

However, privacy systems must be designed responsibly.

They should protect legitimate users while avoiding unclear claims, hidden trust assumptions, or weak cryptographic designs.

Users should ask what information is hidden, what information is public, who can verify the proof, and what data remains stored off-chain.

Jordi Baylina and Decentralized Identity

Decentralized identity lets users manage credentials and proofs without relying entirely on one centralized identity provider.

Jordi Baylina’s iden3 work connects directly with this idea.

In crypto, decentralized identity can support access control, compliance, airdrop eligibility, reputation, governance, anti-sybil systems, and private credentials.

Zero-knowledge proofs can make identity more privacy-preserving by allowing selective disclosure.

For example, a user may prove that they meet a rule without revealing every document or personal detail behind that rule.

This is important because public blockchains are not good places to store sensitive personal data.

Identity systems should minimize data exposure and avoid putting private information directly on-chain.

Baylina’s role in this area helps explain why ZK technology is not only about faster transactions.

It is also about safer digital trust.

Jordi Baylina and DeFi

DeFi means decentralized finance, which includes blockchain-based systems for trading, lending, borrowing, liquidity provision, derivatives, stablecoins, and asset management.

Jordi Baylina is relevant to DeFi because DeFi depends heavily on Ethereum scaling, smart contract security, privacy, and proof systems.

If Ethereum becomes cheaper and faster through Layer 2 systems, DeFi can become more usable for smaller transactions.

If zero-knowledge identity becomes practical, DeFi may support more privacy-preserving compliance and reputation systems.

If zkVMs and proof systems improve, DeFi protocols may be able to verify more complex off-chain computation on-chain.

However, DeFi remains risky.

Users can lose funds through smart contract bugs, oracle failures, liquidation cascades, malicious approvals, bridge failures, and poor governance.

A project connected with respected ZK builders still requires independent review.

Good cryptography improves trust assumptions, but it does not remove financial risk.

Jordi Baylina and Layer 2 Risk

Layer 2 networks are designed to scale base-layer blockchains by moving some activity off the main chain.

ZK-rollups are a type of Layer 2 that use validity proofs to verify off-chain execution.

Jordi Baylina’s work on zkEVM systems makes him relevant to Layer 2 risk education.

Layer 2 systems can reduce fees and improve throughput, but they introduce their own risks.

Users should understand bridge contracts, withdrawal delays, sequencer operation, proof generation, upgrade keys, data availability, liquidity fragmentation, and ecosystem support.

A ZK proof can verify execution correctness, but it does not automatically remove every operational and governance risk.

Users should test small transactions before moving large balances to any new network.

They should also verify official bridges and avoid copied websites that imitate real Layer 2 tools.

Jordi Baylina and ZK Circuit Risk

ZK circuit risk is the risk that a circuit does not correctly express the statement it is supposed to prove.

This risk is important because a proof can be mathematically valid while proving the wrong thing.

For example, a circuit might forget to constrain an important value, allow an invalid witness, or expose information that should remain private.

The academic paper Circom: A Circuit Description Language for Building Zero-Knowledge Applications explains Circom as a language and compiler for designing arithmetic circuits used in ZK systems.

Because ZK circuits are complex, developers need testing, auditing, formal methods, review tools, and careful design patterns.

Baylina’s contribution to ZK tooling helped developers build circuits more easily.

That accessibility is valuable, but it also means more developers need to learn ZK-specific security habits.

Users should be cautious with new ZK applications that have not explained their audits, proving assumptions, and verifier design.

Jordi Baylina and Trusted Setups

Some zero-knowledge proof systems require a trusted setup ceremony.

A trusted setup creates parameters used by the proving and verification system.

If a trusted setup is compromised in certain systems, it may weaken security.

snarkjs includes tools for multi-party trusted setup ceremonies, as described in the official snarkjs repository.

Trusted setup design matters because it affects user confidence in the proof system.

Multi-party ceremonies can reduce trust in any single participant because the system may remain secure if at least one participant behaves honestly and destroys their secret contribution.

Users do not need to run a ceremony themselves, but they should know whether a ZK protocol depends on one.

Developers should clearly document setup assumptions instead of hiding them behind technical language.

Jordi Baylina and Crypto Developers

Jordi Baylina’s work is especially important for crypto developers.

Developers use tools, libraries, examples, and documentation created by earlier builders to create new applications.

Circom and snarkjs helped many developers learn how to create ZK circuits and proofs.

Polygon zkEVM showed how ZK proving could be applied to Ethereum-compatible execution.

ZisK points toward a future where developers may be able to prove more general programs with lower latency.

These contributions matter because developer tools shape what kinds of applications are possible.

Better tools can reduce complexity and improve safety, but they can also make it easier for inexperienced developers to deploy risky systems.

Responsible developers should learn the limits of every tool they use.

Jordi Baylina and Crypto Users

Most crypto users will never directly use Circom, snarkjs, PIL, or a zkVM command-line tool.

They may still benefit from these technologies through wallets, rollups, identity systems, bridges, and dApps.

When a user pays lower fees on a ZK-based Layer 2, they may benefit from zero-knowledge scaling work.

When a user proves eligibility without revealing private information, they may benefit from ZK identity work.

When a smart contract verifies a proof instead of rerunning a full computation, the user may benefit from verifiable computation.

Baylina’s work is therefore part of the background infrastructure that can make crypto easier to use.

Users should still stay cautious.

Advanced infrastructure does not protect against phishing, fake bridges, malicious approvals, poor token design, or unsafe custody habits.

Jordi Baylina and Tokenized Assets

Tokenized assets are real-world or digital claims represented as blockchain tokens.

Jordi Baylina is relevant to tokenization because ZK proofs can help verify information about assets, identities, or compliance without exposing unnecessary data.

For example, a tokenized asset system may need to prove that a user meets eligibility rules without publishing the user’s full identity on-chain.

ZK systems can also support auditability by proving that certain computations were performed correctly.

However, tokenization risk is not solved by ZK technology alone.

A tokenized asset still depends on the issuer, legal documents, custody structure, redemption terms, reserve quality, and jurisdiction.

ZK proofs can improve verification and privacy, but they cannot make a weak legal claim strong.

Users should separate cryptographic proof from real-world asset rights.

Jordi Baylina and Governance

Governance means how a crypto project, protocol, foundation, DAO, or company makes decisions.

Jordi Baylina’s career includes projects that depend on open-source communities, research teams, protocol decisions, and ecosystem coordination.

Governance matters because ZK infrastructure can be technically complex and difficult for normal users to evaluate.

Users often need to trust that teams will manage upgrades, audits, disclosures, and security incidents responsibly.

A project may have strong code but weak governance.

Another project may have good governance but immature technology.

Users should check who can upgrade contracts, pause systems, change proving rules, control bridges, or manage treasury funds.

Founder reputation is useful context, but clear governance is still necessary.

Jordi Baylina and Open Ethereum Values

Jordi Baylina is often associated with Ethereum values such as open-source development, permissionless innovation, security, and community coordination.

His work on tools and infrastructure reflects a builder culture focused on practical implementation.

Open Ethereum values matter because the ecosystem depends on many independent developers sharing ideas, reviewing code, and building public goods.

ZK infrastructure is especially suited to this culture because the math is difficult and benefits from peer review.

Open development can expose mistakes earlier and help the community improve shared systems.

However, open communities can also move quickly and create confusion for users.

Users should rely on official documentation and verified links rather than random social media posts.

Good crypto education helps users benefit from open systems without becoming victims of fake copies or rushed experiments.

Jordi Baylina and Crypto Scams

Public crypto builders can be impersonated by scammers.

A scammer may use Jordi Baylina’s name, photo, fake account, fake interview, fake token launch, fake grant program, fake ZK airdrop, or fake support message to create trust.

Users should be skeptical of any message claiming that Baylina or a related ZK project is offering guaranteed returns, private investment access, or a secret token allocation.

They should also be careful with fake bridges, fake zkEVM migration pages, fake ZisK downloads, and copied GitHub links.

No legitimate developer, founder, support agent, or ZK tool needs a user’s seed phrase or private key.

No proof system requires a retail user to reveal wallet recovery words.

No legitimate wallet support process needs remote device access to protect funds.

Users should verify all links through official websites, official repositories, and trusted documentation.

How Jordi Baylina Differs From a Crypto Project

Jordi Baylina is a person, while Hermez, Polygon zkEVM, iden3, Circom, snarkjs, and ZisK are projects or tools connected with his work.

This distinction matters because users sometimes confuse founders, protocols, tokens, networks, wallets, and applications.

A person can influence technical direction and ecosystem culture.

A tool can help developers build applications.

A protocol can define rules for settlement or proof verification.

A token can have supply, utility, governance rights, liquidity, and price risk.

A wallet can control access to assets through keys and signatures.

Each layer has different risks.

Learning about Baylina helps users understand the background of ZK infrastructure, but it does not prove that every related asset or application is safe.

Common Misunderstandings About Jordi Baylina

One misunderstanding is that Jordi Baylina is a token.

He is a developer and zero-knowledge infrastructure builder, not a cryptocurrency.

Another misunderstanding is that zero-knowledge always means full privacy.

Some ZK systems are built mainly for scalability and may still publish transaction data.

A third misunderstanding is that zkEVM systems remove every Layer 2 risk.

zkEVM systems can improve validity guarantees, but users still need to consider bridge, sequencer, upgrade, liquidity, and governance risks.

A fourth misunderstanding is that ZK tools are safe because they are mathematical.

Mathematics can be strong, but implementations, circuits, parameters, and user interfaces can still fail.

A fifth misunderstanding is that founder reputation guarantees token value.

Baylina’s technical reputation is important, but it does not guarantee the performance, safety, or suitability of any token or application.

Lessons Crypto Users Can Learn From Jordi Baylina

The first lesson is that scaling requires serious cryptographic engineering.

The second lesson is that privacy and verification can work together through zero-knowledge proofs.

The third lesson is that open-source tools can shape an entire ecosystem.

The fourth lesson is that developer infrastructure matters even when users never see it.

The fifth lesson is that ZK circuits must be audited carefully because a valid proof can still prove the wrong statement if the circuit is flawed.

The sixth lesson is that Layer 2 systems improve usability but still carry bridge, governance, and operational risks.

The seventh lesson is that identity systems should protect privacy instead of putting sensitive personal data on public chains.

The eighth lesson is that no founder, developer, or support agent should ever need a seed phrase, private key, or wallet recovery phrase.

Best Practices for Researching Jordi Baylina

Start with official project sources such as ZisK, Circom, snarkjs, iden3, Ethereum documentation, and Polygon technical materials.

Separate Jordi Baylina from the projects, tools, networks, and tokens associated with his work.

Check current dates because roles and project structures can change quickly in crypto.

Use official repositories when downloading developer tools or reading code.

Do not trust social media accounts that copy a founder’s name or image.

Do not send funds to private wallet addresses claiming to represent a ZK founder or project.

Do not enter seed phrases into websites claiming to unlock a zkEVM migration, airdrop, or proof tool.

Review audits, documentation, governance, and official announcements before using any ZK application with meaningful value.
